Golang is a powerful programming language that is widely used in various application scenarios. However, like any other language, it has some shortcomings. In this article, I will discuss some of the downsides of Golang, including its shortcomings and limitations.
- The learning curve of concurrency mechanism is steep
Golang is a language with concurrent programming as its core and has a set of powerful concurrency mechanisms. However, this also makes Golang’s learning curve steep, especially for developers without concurrent programming experience.
Golang’s concurrency mechanisms include channels, coroutines, mutex locks, read-write locks, etc. Developers need to fully understand the working principles of these mechanisms and use them correctly in the code. This can take some time and effort, and it's easy for beginners to get bogged down.
- The error handling mechanism needs to be improved
Golang’s error handling mechanism is relatively unique. It uses two functions, panic and recover, to handle errors. Although this mechanism is very powerful, it can also easily make the code flow difficult to understand.
In addition, if you want to use your own defined error types, you need to follow some fixed coding standards. This may be a bit annoying for some developers.
- Lack of generic support
Golang’s lack of generic support is one of its major shortcomings. Generics are a very useful programming feature that is widely used in other languages. It helps developers create more versatile code, thereby improving code reusability and maintainability.
Although Golang provides some compromise solutions, such as using interface types to implement some generic features, this solution is not a completely ideal solution.
- Insufficient dependency management
Golang’s dependency management is also one of its shortcomings. In Golang, although there is a standard dependency management tool go mod, in actual use, the version management of some dependent libraries is not very good. Since there is no clear limit on dependency version numbers, version conflicts are prone to occur.
In addition, the location of Golang's dependency libraries is a bit confusing. Some are placed under GOPATH and some are placed under the vendor directory. Developers need to continuously learn and master new dependency package management skills.
- The performance is not as good as C or C
Although the concurrency mechanism and garbage collection mechanism provided by Golang can greatly improve development efficiency, in terms of performance, Golang cannot compete with Comparable to languages like C or C.
When processing large-scale, highly concurrent data, Golang's performance often becomes a major bottleneck. At this point, developers may need to use C or C++ for optimization.
Summary
Golang is a very excellent programming language, but it also has some shortcomings. Especially in terms of error handling mechanism, generic support and dependency management, Golang still has many areas that can be improved and perfected. However, we believe that the continuous efforts and improvements of the Golang community will definitely make Golang more stable, efficient and flexible.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
